Which of the following statements is/ are false about mode of heat transfer?

I. In radiation, heat is transfered from one medium to another without affecting the intervening medium
II. Radiation and convection are possible in vaccum while conduction requires material medium.
III. Conduction is possible in solids while convection occurs in liquids and gases.

II only

-Conduction and convection are not possible in vacuum, they require medium, as in convection, heat transfer takes place only by motion of particles in the medium and in vacuum particles are not present. While radiation is possible in vacuum.
